20.500.12556/DiRROS-15800 Report of RILEM TC 267-TRM phase 2 optimization and testing of the robustness of the R3 reactivity tests for supplementary cementitious materials The results of phase 1 of an interlaboratory test, coordinated by the RILEM TC 267-TRM “Tests for Reactivity of Supplementary Cementitious Materials” showed that the R3 (rapid, relevant, reliable) test method, by measurement of heat release or bound water, provided the most reliable and relevant determination of the chemical reactivity of supplementary cementitious materials (SCMs), compared to other test methods. The phase 2 work, described in this paper aimed to improve the robustness of the test procedure and to develop precision statements for the consolidated test procedure. The effect of the pre-mixing and mixing conditions, and the impact of the mix design on the test method robustness were assessed and fixed for optimal conditions to carry out the R3 heat release test. The effect of the drying step was evaluated to define the R3 bound water test procedure in more detail. Finally, the robustness of the consolidated final test methods was determined by an interlaboratory study to define the precision statements. supplementary cementitious materials reactivity test bound water mineralni dodatki test reaktivnosti vezana voda true false true Springer Netherlands Angleški jezik Slovenski jezik © The Author(s) 2022 Neznano 2022-11-17 15:04:18 2023-04-26 08:39:16 2023-04-27 03:37:55 0000-00-00 00:00:00 2022 0 0 Article no.: 92; Opis vira z dne 20. 4. 2022; str. 1-14 Vol. 55 Mar. 2022 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2022-03-28 620.1/.2 1871-6873 10.1617/s11527-022-01928-6 105420803 https://link.springer.com/article/10.1617/s11527-022-01928-6 1 58a370c0-6678-11ed-a69a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20900 RAZ_Avet_Francois_2022.pdf RAZ_Avet_Francois_2022.pdf 1 4D4AF2D34C46412CCC4526C37C3C388B 1a44a87ce5d8f2e0f07a8d47a8c5a8323fd15ea6f4a54d6a3314f38be790acf9 627684e1-79ee-11ed-8925-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21030 Zavod za gradbeništvo Slovenije 0 0 0
